UR5P3011 Phase failure monitoring B The output relay R switches into off-position (yellow LED not illuminated), when one of the three phases fails. Asymmetry monitoring C The output relay R switches into off-position (yellow LED not illuminated), when the asymmetry exceeds the value set at the ASYM-regulator. Reverse voltages of a consumer (e.g. a motor which continues to run on two phases only) do not effect the disconnection.

Temperature monitoring of the motor winding with fault latch If the supply voltage U is applied (green LED illuminated) and the cumulative resistance of the PTC-circuit is less than 3.6kȍ (standard temperature of the motor), the output relay switches into on-position.

Pressing the test/reset key under this conditions, forces the output relay to switch into off-position. It remains in state as long as the test/reset key is pressed and thus the switching function can be checked in case of fault. The test function is not effective by using an external reset key.

When the cumulative resistance of the PTC-circuit exceeds 3.6k ȍ (at least one of the PTCs has reached the cut-off temperature), the output relay switches into off-position (red LED illuminated). UR5R1021 The output relay R switches into on-position again (red LED not illuminated), if the cumulative resistance drops below 1.65k ȍ by cooling down of the PTC and either a reset key (internal or external) was pressed or the supply voltage was disconnected and reapplied.

Note Use cables with low capacity for wiring the probes especially with extended wiring length! Following processes are suggested for the adjustment: • The existent time delay should be to minimum (0.5s). • The function selector switch must be in position pump down. • Turn the sensitivity controller slowly clockwise from "min." to "max." until the relays switches into on-position (probes must be in dipped state). • The moistened probes should be taken out of the liquid to control if the relays switches into off-position. If the relays doesn't switch into off-position, turn the sensitivity controller slightly back to "min." (counter clockwise). • Set the existent time delay to desired value to fade out a short term moisten the probes by waves in the liquid. • Set the function selector switch to desired position (either pump up or pump down).

If single-phase monitoring is required, unused input terminals (L) must be connected to mains voltage to have proper L-N voltage on the terminals L1 , L2 and L3 . A phase failure can not be detected, if the reverse voltage coming from the load exceeds the threshold Us relay.

When the supply voltage U is applied, the output relays switch into on-position (yellow LED illuminated) and the set interval of the start-up suppression (START ) begins (green LED U flashes). Changes of the measured voltage during this period do not affect the state of the output relay. After the interval has expired the green LED is illumi-nated steadily. For all the functions the LEDs "MIN" and "MAX" are flashing alternating, when the minimum value for the measured voltage was chosen to be greater than the maximum value. Overvoltage monitoring When the measured voltage exceeds the value adjusted at the MAX-regulator, the set interval of the tripping delay (DELAY ) begins (red LED MAX flashes). After the interval has expired (red LED MAX illuminated), the output relays switch into off-position (yellow LED not illuminated). The output relays again switch into on-position (yellow LED illuminated), when the measured voltage falls below the value adjusted at the MIN-regulator (red OVER, 1.1 LED MAX not illuminated). If the fault latch is activated (OVER+LATCH ) and the measured voltage remains OVER + LATCH above the MAX-value longer than the set interval of the tripping delay, the output relays remain in the off-position even if the measured voltage falls below the value adjusted at the MIN-regulator. After resetting the failure (interrupting and reapplying the supply voltage), the output relays switch into on-position and a new measuring cycle begins with the set interval of the start-up suppression (START ). Undervoltage monitoring When the measured voltage falls below the value adjusted at the MIN-regulator, the set interval of the tripping delay (DELAY ) begins (red LED MIN flashes).

For all the functions the LEDs MIN and MAX are flashing alternating, when the minimum value for the measured voltage was chosen to be greater than the maximum value. If a failure already exists when the device is activated, the output relays remain in off-position and the LED for the corresponding threshold is illuminated. Undervoltage monitoring When the measured voltage (mean value of phase-to-phase voltages) falls below the value adjusted at the MIN-regulator, the set interval of the tripping delay (DELAY ) begins (red LED MIN flashes). After the interval UNDER, 2.1 has expired (red LED MIN illuminated), the output relays switch into off-position (yellow LED not illuminated).

After the interval has expired (red LED MIN illuminated), the output relays switch into off-position (yellow LED not illuminated). Phase sequence monitoring Phase sequence monitoring is selectable for all functions. If a change in phase sequence is detected (red LED SEQ 2.3 SEQ illuminated), the output relays switch into off-position immediately (yellow LED not illuminated). UR6U3052 Phase failure monitoring If one of the phase voltages fails, the set interval of the tripping delay ( DELAY ) begins (red LED SEQ flashes). After the interval has expired (red LED SEQ illuminated), the output relays switch into off-position (yellow LED not SEQ 2.4 illuminated). Reverse voltages of a consumer (e.g. a motor which continues to run on two phases only) do not effect the disconnection but can be monitored by using a proper value for the asymmetry. Asymmetry monitoring If the asymmetry of the phase-to-phase voltages exceeds the value set at the ASYM-regulator, the set interval of the tripping delay (DELAY ) begins (red LED ASYM flashes). After the interval has expired (red LED ASYM illuminated), the output relays switch into off-position (yellow LED not illuminated). If the neutral wire is connected 2.5 to the device, the asymmetry of the phase voltages referred to the neutral wire (Y-voltage) is monitored also. In that case both values of the asymmetry are evaluated and if one of the values exceeds the value set at the ASYM- regulator, the set interval of the tripping delay ( DELAY ) begins (red LED ASYM flashes). After the interval has expired (red LED ASYM illuminated), the output relays switch into off-position (yellow LED not illuminated). Loss of neutral wire by means of evaluation of asymmetry A break of the neutral wire between power line and machinery is detected as soon as asymmetry between phase-to-phase voltage and neutral wire occurs. If the asymmetry exceeds the value set atthe ASYM-regulator, 2.6 the set interval of the tripping delay ( DELAY ) begins (red LED ASYM flashes). After the interval has expired (red LED ASYM illuminated), the output relays switch into off-position(yellow LED not illuminated).

If the supply voltage U is applied (green LED illuminated) and the cumulative resistance of the PTC-circuit* is less than 3.6kȍ (standard 5.1 temperature of the motor), the output relays switch into on-position.

Motor Monitoring If the motor is not running, the light ( H1 ) will be off; if the motor is running, the light will be on. In the event of faulty operation of the motor (F1 ), the light will flash on-off.

Contact monitoring with Change Over Contact During regular operation the light will be on ( H2 ); in the event of an interruption, the light will flash on-off (H3 ).

High Reliability Lighting To maintain the functionality of acoustic and optical collective signalling, connecting a parallel resistor is recommended (at 24 V, 2K2 ȍ / ½ W).

Acoustic Signalling In the event of an interruption, the horn will signal approx. 15 sec. afterwards ( H5 ). It can be reset by pressing the Acknowledge (B4 ) key.

YY494107 YY494107 YY494107 w Schrack-Info • Despite their compact size the diode combinations DBS10 (YY494007) and DBS01 (YY494107) are suitable for up to 10 indicators. If there are light bulbs/glow lamps or LEDs for signalling operating states, integrating the diode combination can be a simple way to retrofit an alarm verification. By connecting multiple combinations it is possible to scan any number of alarms. Every diode combinations contains a protective diode, which limits the impact of a defective individual diode on other components of the system (e.g. contactors). Both diode combinations DBS10 and DBS01 can be used as protection diodes for relays and contactors. • The DBS10 and DBS01 have different polarities, which are explained in detail in the circuit diagrams • Both types are compatible with the 11 pole plug-in socket YMR78700 w Dimensions DBS10 & DBS01 (mm)
